It is evident from an examination of Neofiber that the genus stands
intermediate between the aberrant Fiber and the normal arvicoline
genera. The skull, the large head, and peculiar ears, and the heavy
form show its affinity to Fiber, while the feet and tail prove its close
relationship to the other arvicolas.

It will be interesting to know how far the habits of this animal re-

semble those of the ordinary muskrat. 2 ee a Prk, Ma. SA. -

ON A COLLECTION OF BIRDS MADE BY MESSRS. J. E. BENEDICT
AND W. NYE, OF THE UNITED STATES FISH COMMISSION
STEAMER ‘‘ ALBATROSS.”

By ROBERT RIDGWAY.

A collection of birds made by Messrs. J. E. Benedict and W. Nye,
naturalists accompanying the steamer ‘ Albatross” on her winter’s
cruise through West Indian waters and along the southern coast of the
Caribbean Sea, although not extensive, is of much interest. This is
especially true of those collected on the island of Old Providence, 250
miles narth of Aspinwall, all the species from that locality being new to
science.

The species collected at the different stations are given under sepa-
rate headings:

1, Mimus gilvus rostratus, subsp. nov.

SUBSP. CHAR.—Similar to true M. gilvus, but with much larger bill,
the lower parts more purely white, with no grayish shade across the
jugulum, and the upper parts lighter gray. 4 (type, No. 97927, U.S.
Nat. Mus.): wing, 4.35; tail, 4.90; graduation, .80; all the feathers
tipped with white, that on outer feather 1.40 in length, measured along
inner side of shaft; culmen, 1.05; bill from nostril, .65; depth at base,
.30; tarsus, 1.30; middle toe, .82. 2 (type, No. 97928, U.S. Nat. Mus.):
wing, 4.20; white on inner web of outer tail-feather, 1.25; culmen, 1.00;
bill from nostril, .62; depth at base, .28; tarsus, 1.28; middle toe, .85.

2. Dendroica rufopileata, sp. nov.

Sp. CHAR.—Adult é (type, No. 97930, U.S. Nat. Mus.): Forehead and
crown uniform chestnut-rufous, abruptly defined all round. Upper
parts yellowish olive-green, the wings slate-dusky, with broad and dis-
tinct pure yellow edgings on greater wing coverts and tertials, the
outer webs of the former being almost wholly yellow; primaries and
secondaries narrowly edged with olive-yellow. Inner webs of rectrices
(except middle pair) wholly clear primrose-yellow; outer webs dusky,
edged, especially on lateral feather, with yellow. Sides of head (includ-
ing lores and superciliary region back to above auriculars) and entire
lower parts, pure gamboge-yellow, the jugulum and breast broadly, but
not very sharply, streaked with rufous. Bill black, legs and feet
brownish. Wing, 2.30; tail, 2.00; culmen, .50; depth of bill, .14; tar-
sus, .75; middle toe, .40.

Adult 2 (type, No. 97931, U.S. N ab: Mus.): Differing from the male in
lacking any trace of LotR on crown or streaks on breast. Yellow be-
neath decidedly less pure. Bill light brownish, the maxilla dusky.

174 PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM.

Wing, 2.30; tail, 2.00; culmen, .45; depth of bill, .12; tarsus, .75; middle
toe, .42.

The nearest ally of this species is D. capitalis, Lawr., of Barbadoes,
which differs in having the pileum of a very dark, rich chestnut, in
having the entire sides and flanks, as well as the breast, sharply
streaked with rich chestnut, the yellow of the lower parts and the olive-
green of the upper surface much deeper, and the bill much stouter.

There are two males and two females in the collection.

3. Icterus curasoێnsis, sp. noy.

Sp. CHAR.—Similar to I. xanthornus (Gm.), but with the bill much
longer, more attenuated, and more acute, the white markings of the
wings much broader, and the yellow color paler. Adult 3 (type, No.
97913, U.S. Nat. Mus.). Lemon-yellow, including lesser and middle
wing coverts, rather deeper beneath, especially on the breast and sides
of jugulum, the back and scapulars with a very faint olivaceous tinge.
Lores, extreme anterior portion of malar region, chin, throat, wings
(except lesser and middle coverts), and tail, black. Greater wing-
coverts broadly tipped and tertials broadly margined with white; sec-
ondaries more narrowly, but still very distinctly, margined with white,
but the white extending not quite to the tips of the coverts; second to
fifth primaries, inclusive, broadly edged with white at the base, the —
white extending for .45 of an inch beyond the tips of the primary
coverts on the third quill; all the primaries, except the first, narrowly
edged with white from about the middle portion to the tip. Three
outer tail-feathers narrowly bordered at tips with grayish-white, and
all the rectrices with an inch (more or less) of their basal portion pale
lemon-yellow, more whitish on inner web, the shaft of this portion of
the feathers being pure white. Bill deep black, the basal angle of the
mandible plumbeous ; legs and feet dark plumbeous. Wing 3.70, tail
3.70, graduated for .60 of an inch; culmen 1.10, bill from nostril .80,
from basal angle of mandible 1.08, depth of bill through base .50:
tarsus 1.00, middle toe .70.*

The examination of specimens of J. xanthornus in this connection
renders desirable some remarks on the latter species. In Dr. Sclater’s
recent review of the Icterinet (Ibis, July, 1883, pp. 368, 369), the habitat
of I. xanthornus is given as follows: ‘ Coast-region of Colombia and
Venezuela, Trinidad, Guiana, and Rio Negro. Santa Marta (Stmons) ;
Carupano, Venezuela (Goering); Demerara (Brown); Rio Brancho

*The measurements of the longest-billed specimen among five adultsof J. canthornus,
from the main land of northern and eastern South America (Colombia to Brazil), are
as follows: Wing 3.65, tail 3.65, culmen .88, bill from nostril .60, from basal angle of
mandible .88, depth of bill through base .50, tarsus 1.05, middle toe .80. The shortest-
billed example has the culmen only .75 of an inch long.

(Natt), while among the synonyms there is no mention of Oriolus mewi-
canus (part) LINN., ed. 12, p. 162, No. 13, Icterus xanthornus var. a.
dubusti, DuBOIS, I. x. var. 8. marginalis, DuBoIsS, I. auratus, CASs.
(nec. Br.), and Xanthornus nigrogularis, HAHN, all of which (with
possibly the exception of the last) appear to be referable to the present
species. The U. S. National Museum possesses a skin (No. 32769),
from Verreaux, which, on the label, is marked as from “ Mexique,” and
which corresponds exactly with DuBoIs’ “ var. 3. marginalis,” which is
stated to have come from Panama; also a skin which I selected from a
collection of Guatemalan birds (in the hands of a dealer), which,
although it may not have really come from that country, nevertheless
seemed to agree in “make” with the other skins, is different from any
South American examples, and, furthermore, agrees in certain charac-
ters with the skin said to have come from Mexico. The latter is the
specimen noticed by Mr. Cassin (as below) under the name “ auratus,”
and bears this name, in his handwriting, on the label. On the same
label are also inscribed, ‘“ Icterus xanthornus, DAUD.,” by Verreaux, and
‘“Tcterus nigrogularis, BONAP.,” by Mr. Lawrence. The specimen in
question differs from all South American examples of the species in the
National Museum (six in number) in the following particulars: (1)
Large size, the wing measuring 4 inches, the tail 5.90, against 3.70 and
3.70, respectively, the maximum in the South American series; (2) de-
cidedly purer yellow color of the back, which is hardly less clear in color
than the breast, all the South American skins having a more or less
olivaceous tinge on the dorsal region; (3) distinct white speculum at
the base of the primaries, extending backward for nearly half an inch
beyond the tips of the primary-coverts. As to the last-mentioned fea-
ture, most of the South American examples* have more or less of an
indication of this white speculum; but in none is it nearly so large,
while the white edgings to the secondaries are also less conspicuous,
although the approach is quite near in two of them. These white
markings are, however, very variable in their extent and development
in different individuals, not only of this species but many others also,
and they also vary in distinctness according to the age of the feathers,
becoming in very old feathers so much abraded as to have almost dis-
appeared, except where broadest. As a character, therefore, they need
searcely be taken into account.

The specimen supposed to be from Guatemala I should be disposed
to refer to the same form as the one said to have come from Mexico,
apart from any circumstantial evidence as to its origin, on account of

the fact that it agrees with the latter in the rich and nearly pure yellow
of the back, and large size, although the dimensions are but little
greater than those of the largest of the South American series, the wing
measuring 3.90 and the tail 3.75 inches.

In conclusion, assuming that there may be two separable races of this
species belonging respectively to Middle America and Northern South
America, east of the Andes—a point regarding which I must confess
myself as not quite satisfied—their synonymy may be arranged as fol-
lows:

4. Zenaida ruficauda, Bonap.?
Or sp. nov. Zenaida vinaceo-rufa, Ridgw.?

An adult female Zenaida (No. 97933, U. S. Nat. Mus.) is perhaps refer-
able to Bonaparte’s Z. ruficauda (Consp. I, 1854, 83), described as from

PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. 177

Vol. VEE, No. 12% Washington, DC. July 29, 2884.

New Granada, but differs in several respects from the description of
that species. In the first place, there are fourteen rectrices, which would
make it referable to the so-called genus Zenaidura, which includes
another short-tailed species, the Z. yucatanensis, LAWR. from Merida,
Yucatan (cf. “The Auk,” Jan., 1884, p. 96). In the second place, the
markings on the side of the head do not agree. Bonaparte (l. c¢.)
says: “*Nucha plumbea, macula suboculari, vittaque postoculari, albo-
limbata, nigro-violaceis.”. The bird before me has the nape grayish
brown, like the pileum; the postocular streak and subauricular (not
subocular) spot are black (the latter glossed with steel-blue), and
wholly destitute of white or light colored edgings. In view of possible
specific or subspecific difference from Z. ruficauda I give herewith a full
description of the Curacoa specimen, and, if distinct, would propose for
it the name Zenaida vinaceo-rufa.

Adult @ (No. 97933, U.S. Nat. Mus.): Upper parts grayish brown,
becoming more decidedly brown on the tertials and posterior scapulars ;
primaries dusky, very narrowly edged with whitish; two innermost
tertials and corresponding greater wing coverts marked with a longitu-
dinally oval spot of black. Middle pair of tail-feathers and basal two-
thirds (approximately) of other rectrices grayish brown (the inner web
decidedly gray), this color bounded terminally by a black bar (broadest
on inner web), the remaining portion of the rectrices rich cinnamon-
rufous; outer web of lateral tail-feather without the black bar, cinna-
mon-rufous, fading into light vinaceous basally. Forehead and sides of
head light isabella-brown, with a slight tinge of vinaceous, fading into
buffy whitish on chin and upper part of throat. A postocular black
line bordering upper edge of auriculars, and beneath the latter a spot of
glossy blue-black. Sides of the neck richly glossed with metallic sol-
ferino-purple, changing to golden. Lower parts brownish vinaceous,
purer vinaceous posteriorly, where deepest on the crissum. Lining of
wings, axillars, and flanks, bluish cinereous. Bill, black; feet, pale
brownish (red in life?). Wing, 5.40; tail, 3.50, graduated for .90 of an
inch; culmen, .55; tarsus, .85; middle toe, .80.

W.—ISLAND OF OLD PROVIDENCE, CARIBBEAN SEA, 250 MILES NORTH
OF ASPINWALL (April 4-9, 1884).

i. Certhiola tricolor, sp. nov.

Sp. CHAR.—Similar to C. bahamensis, but larger, the upper parts
‘darker, yellow on rump more extended, and posterior lower parts pale
‘yellowish. Adult 3 (type, No. 97844, U. S. Nat. Mus.): Above dull
‘black, including the whole of the exposed portion of the tertials and
‘secondaries. A broad and very distinct superciliary stripe of pure
white, extending from the nostrils to the occiput; primaries with a
large basal speculum of white, extending for about .40 of an inch
beyond the ends of the coverts; basal half of inner web of all the sec-
ondaries pure white; three outer tail-feathers broadly tipped with white.
Lower half of rump lemon-yellow. Broad band on side of head, involv- -
ing lores and auriculars, and passing beneath but not above the eye,
black; this band much narrower anteriorly, and gradually widening
posteriorly, where confluent with the black of the nape. A small black
line along the lower edge of the rictus. Chin, throat, jugulum, and
cheeks uniform grayish white; whole breast and upper part of abdo-
men lemon-yellow, changing to olive-gray on the flanks and dull yel-
‘owish white on anal region and crissum. Lining of wing pure white,
the bend bright yellow. Bill, deep black; feet, dusky. Wing, 2.60;
tail, 1.90; culmen, .55; depth of bill at base, .20; tarsus, .80; middle
toe, .50.

Young, first plumage (type, No. 97845, U.S. Nat. Mus.): Above dull
grayish brown, the back indistinctly clouded with dusky, the forehead
mostly dull black (uew feathers); rump dingy olive-yellow. An indis-
tinct superciliary stripe of pale dingy yellow, becoming nearly white
anteriorly. A narrow loral stripe of dusky passing beneath the eye,
put changing to dull grayish brown, and continuing, broadly, over the
auriculars to the nape. Lower parts dingy olive-yellow, brighter on
the breast and upper part of abdomen; anal region and crissum pale
buffy yellowish. Lining of wing pure white, changing to yellow along
the edge of the wing. Wing-speculum smaller than in the adult, but
still very Conspicuous.

It is somewhat remarkable that the nearest ally of this species should
be the Bahaman CO. bahameusis. It requires comparison with no other,
except, perhaps, OC. caboti, Baird, of Cozumel Island, Yueatan, which I
have not been able to examine in this connection. ;

‘2. Vireosylvia graidior, sp. nov.
Sp. cuAR.—Largest known species of the genus, somewhat ramble
V. barbadense, but much vrayer, the submalar urs much narrower,

PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. 179

and bill altogether larger and stouter. Adult ¢ (type, No. 97846, U. 8.
Nat. Mus.): Pileum and nape brownish gray, the first darker laterally,
but the dusky hardly forming a distinct streak; the gray of the nape
gradually assuming a more olive tinge on the back, this increasing in
intensity posteriorly, the rump and tail being decidedly olive-greenish.
A distinet superciliary stripe of pale brownish gray, or dull grayish
white, bordered beneath by a loral and postocular streak of dusky gray;
auriculars and. sides of neck pale olive-grayish, fading gradually intu
dull white on malar region, chin, and throat; the latter bordered on each
side by a narrow line of dusky gray. Remaining lower parts dull white
medially, light greenish olive laterally, the anal region, crissum, and inner
edges of rectrices pale buffy yellow; lining of wing white, tinged with
sulphur-yellow; a very faint brownish gray shade across the jugulum.
Maxilla brownish black, paler along tomium; mandible pale browish

3. Vireo approximans, sp. nov.

Sp. CHAR.—Similar to V. crassirostris, Bryant, butrather paler above,
the yellow supraloral streak much less distinet; the yellowish postocular
spot obsolete, and tail more decidedly rounded or graduated. Adult é
(type, No. 97847, U. S. Nat. Mus.): Pileum and nape brownish gray,
changing to grayish olive on the back, the ramp, upper tail-coverts, and
outer web of rectrices more decidedly olive-greenish; wings dusky,
the middle and greater coverts broadly tipped with yellowish white, and
edged with olive; tertials broadly edged with dull whitish, the remain-
ing remiges more narrowly edged with lght olive-green, changing to
pale grayish toward ends of the feathers. A broad and rather distinct
supraloral stripe or bar of pale buffy yellow; upper eyelid with a bar of
dusky grayish; a very indistinct brownish gray loral or anteorbital
spot. Lower parts pale buffy yellow, paler on anal region and crissum,
the sides grayish olive. Maxilla dark brown, mandible pale brownish
(in dried skin); legs and feet dusky (plumbeous in life?): Wing, 2.45;
tail, 2.20; graduated for .20 of an inch; culmen, .60; bill from nostril,
.o2; depth at base, .20; width, .23; tarsus, .90; middle toe, .45.

Itis not a little remarkable that this species, like the Certhiola from the
same locality, should have its nearest ally ina Bahaman species ( V.crassi-
rostris, Bryant). The resemblance to the latter is indeed so close that
I hesitated to separate it, but finally concluded to do so upon the detec-
tion of certain characters which, though slight, do not occur in either
of the four examples of V. crassirostris now before me. The latter pre-
sent great variations in color, two of them being bright buffy yellowish
beneath, with the supraloral bar intense sulphur- or lemon-yellow, while
the other two are dull buffy whitish beneath, with the supraloval mark
pale dingy yellow. With these latter the piesent bird agrees most

The present bird certainly agrees much better, both in coloration sad
measurements, with V. crassirostris than with V. ochraceus, notwith-
standing the latter is its nearer neighbor geographically.

4. Hlainea cinerescens, sp. nov.

Sp. CHAR.—Adult 6 (type, No. 97849, U.S. Nat. Mus.): Upper parts
deep brownish gray, without trace of olive tinge, somewhat lighter on
the ramp and browner on the upper tail-coverts; feathers of the cen-
tral portion of the crown pure white beneath the surface; wings dusky,
the greater and middle coverts broadly and distinctly, but not sharply,
tipped with light brownish gray, passing into white at the margin; ter-
tials broadly edged with grayish white, and secondaries narrowly mar-
gined with the same to within about .25 of an inch of the tips of the
greater coverts; primaries very narrowly margined with whitish, be-
coming browner basally. Sides of head and neck uniform, slightly
brownish, ash-gray, fading gradually into grayish white on the chin and
throat, the entire sides and flanks, however, about the same shade as the
sides of the neck, and jugulum distinctly, though not abruptly, pale
grayish; abdomen and anal region white ; lower tail-coverts pale gray-
ish brown beneath the surface, the tips broadly white. Mavxilla brownish
black, mandible pale brown, tipped with blackish ; legs and feet black,
Wing, 3.45; tail, 3.30, forked for about .15 of an inch; culmen, .68;
bill from nostril, .35; tarsus, .90; middle toe, .55

Adult 2 (type, No. 97848, U.S. Nat. Mus.): Similar tothe ¢ in color.
Wing, 3.15; tail, 2.90; culmen, .60; tarsus, .80; middle toe, .50.

This species is sBekncoranan by its ashy ieee there being no
trace whatever of any olive or yellowish tinge. Its nearest ally is per-
haps the Antillean EH. martinica (Linn.).
